We are putting in a 34x60 single threshold Swanstone showerbase and tiling the walls. My husband would like to have a 30" or so swinging door (on the 60" side), rather than a double door. This will entailputting a wall on either side of the threshold edge to fully enclose the base (with room for the door of course).I am concerned about potential leakage, and in general, just if it is a good idea to even stray fromthe original intent on how the product should be installed. Sage advice appreciated.
